Eglot: symbol highlighting now done in eldoc-documentation-functions

Even though highlighting the thing at point isn't really producing
documentation at point, theory and practice have shown that using
eldoc-documentation-functions for this is a feasible way to avoid
reimplementing all the idle timer logic for such functionality.

In fact, we were already using ElDoc for this purpose, but this commit
makes it so the new eglot-highlight-eldoc-function is a first class
citizen in eldoc-documentation-functions, so users can manipulate it if
so desired.

* lisp/progmodes/eglot.el (eglot--managed-mode): Use
eglot-highlight-eldoc-function
(eglot-hover-eldoc-function): Don't mix highlighting with hover.
(eglot-highlight-eldoc-function): Rename and rework from
eglot--highlight-piggyback

Pacify -Wanalyzer-use-of-uninitialized-value

With ‘configure --enable-gcc-warnings’,
gcc (GCC) 14.2.1 20250110 (Red Hat 14.2.1-7) on x86-64
complained, as it apparently did not want to assume that enum
variables have one of the listed values.
Work around the problem by using tables rather than
switch statements.  This gives up a little static
checking but I don’t see any other easy way to pacify
GCC without disabling the warnings entirely.
* src/pdumper.c (dump_fwd_int, dump_fwd_bool, dump_fwd_obj)
(dump_fwd_buffer_obj, dump_fwd_kboard_obj):
Last arg is now void const * so that these functions’ addresses
can all be put into the same array.
(dump_fwd, dump_anonymous_allocate_posix, dump_map_file_posix):
Use an array rather than a switch.

Tweak .gitattributes

Use dired--inhibit-auto-revert for fixing bug#71264

The original fix bound auto-revert-mode to nil which had the side-effect
of disabling auto-revert forever in this buffer because
auto-revert-handler removes the buffer from auto-revert-buffer-list when
it's called but auto-revert-mode is nil.

* lisp/dired.el (dired-internal-do-deletions): Bind
dired--inhibit-auto-revert during deletion (bug#71264).
